IMPROVED INHALER FOR MEDIGAL PURPOSES.

To all'ughom 'it 'ma/y concern Be it known that I, J OHN P. BBOWER, ofSyracuse, in the county of Onondaga, and State of New York, haveinvented certain new and useful Improvements in Inhalers for MedicalPurposes, and in nasal douches, by which I am enabled to combinethe twoinstruments in one, or otherwise; and I do hereby declare and. ascertainmy said invention as follows. referring to the accompanying drawing, inwhich- Figure l is an exterior view of the instrument.

Figure 2 is a vertical section.

Figure 3 shows a general view of the nasal douche, as heretofore used.

Articles for the above-named purposes have been made of glass or metal,or both combined. rIhe nasal douche was complex and expensive, having anopening at or near the bottom, difficult to make in glass, andexpensive,I (this is seen in fig. 3,) and it was less convenient than myimproved one.

Ihe nature of my improvement is to perfect and cheapen the instrumentsabove named, by vso constructing them as to render a single instrumentcapable of diverse uses, and forming it of pottery, or like plasticsubstance, by which its construction is cheapened andrendered moreefficient than was heretofore possible in the use of glass and like'substances, and

' thus to bling the inhaler and nasal douche (heretofore limited onaccount of expense and difficulty of operation) into general use. t

My improvements are for the purpose of cheapening the instruments, (andthus bringing them into more general use,) and rendering them moreconvenientand eiiicient.

The construction is as follows:

First, theinh'aler, which consists of a plain reservoir, c, formed likea large-necked bottle, or any other convenient figure that isappropriate, I form of porcelain or any kind of pottery-ware, renderingVit especially` fitted for hot inhalations. l Into this reservoir a isfitted a close stopper of cork, or other suitable substance, throughwhich a pipe, b, of new construction, and also made of earthenware,passes. The pipe b has an aperture, c, extending down from its upper endto a point below the stopper, where .it opens, and terminates throughthe side of the pipe, as clearly seen in fig. 2, Opening into theinterior of -the reservoir a, at the top.v Another opening, d, in thepipe commences just above thecork, and extends down to the end 'ofthepipe, near the bottom of the reservoir, thus forming two openings, orconduits, into the reservoir, at the vtop and bottom thereof, with onepipe.

Secondly, by attaching a flexible tube, g, to the top 0f pipe b, abovedescribed, I-co'nvert the inhaler ,into a nasal douche, by inverting it,and raising the reservoir above the mouth of the tube, when properlyinserted iu the nostril, it being obvious that the liquid contained inthe reservoir will thereby run out with a force due to the elevation,-the opening`din the pipe b, supplying the interior of the reservoirwith air above the liquid which it thus displaces.

It is obvious to the practical manufacturer that the parts .abovedescribed'would be much more difficult and expensive to manufacture inglass than in anykind of earthenware, and that it would not? endure thehigh` poses set forth.

2. Forming a nasal douche,'by attaching a flexible pipe, g, to aninhaler or instrument, substantially as 'above described, and reversingthe reservoir, inthe manner and for the purposes specified.

' In testimony whereof, I hereto subscribe my name.
